The less surface area the grille has, the less reflections there are. Which for the M1060 is ideal IMO.
This is the one one I have but since I got my M1060 early on it was the only honeycomb one at the time. If I was to get some grilles now I would get
this one since I think it looks better (I believe it's also the one OldDude04 has).
Fazors are essentially Soundwave guides that you attach under the pads. I can't comment on how it affects the sound since I don't have Fazors installed on my set but others might be able to say how well they work. I haven't experimented with them since I didn't want to rip off my vegan pads to try them.
